P T Phase Diagrams Of Cu Cu 2 O Cuo Al Al 2 O 3 And Mg Mgo Systems Download scientific diagram | p t phase diagrams of cu cu 2 o cuo, al al 2 o 3 , and mg mgo systems. 1 2cu 2 os o 2 g = 4cuos; 2 4cus o 2 g = 2cu 2 os; 3 4 3als,1 o 2 g = 2 3al 2 o 3 s; 4. Thermo calc software is used to reassess the equilibrium temperature composition phase diagram at 1 atm and to deduce the thermodynamic properties of cu–o binary system at t = 1500 k. the phase diagram showed one single phase which is the non stoichiometric cu ionic liquid other than elemental cu and o at the terminals, in addition to cu 2 o.

P T Phase Diagrams Of Cu Cu 2 O Cuo Al Al 2 O 3 And Mg Mgo Systems The interstice of lattice fingers in fig. 6(b) is 0.24 nm, which is closer to the lattice spacing of cu 2 o (111) (0.247 nm) 38 than cuo (002) (0.253 nm). 39 under the experimental condition of in. Fig. 4 oxygenpressure of cu o melts at the typical variation ofthe xygen pressure ofcu o melts 1352 ~ (1625 k) over a wide oxygen concentration range is hown ifig. 4, which is adopted from [83sch]. t temperature e of 1625 k is lightly above the critical temperature ofthe miscibility 2 gap. 1. 1352~ f . 0. 4.2. solid cu 2 o and cuo. thermodynamic properties of solid stoichiometric compounds cu 2 o and cuo have been well studied. a comprehensive review of the experimental data was reported by hallstedt et al. [13] and their optimized thermodynamic functions of solid cu 2 o and cuo were accepted in the present study. 4.3. liquid phase. The p type semiconductor copper oxide has three distinct phases cu 2 o, cuo, and cu 4 o 3 with different morphologies and oxidation states of the copper ions. we investigate the structural stability and electronic band structure of all three copper oxide compounds using ab initio methods within the framework of density functional theory and consider different exchange correlation functionals.
